When the suspender rotates, since the first gear drives the adjacent suspender to rotate by the same angle, an isosceles triangle can be formed between the adjacent two suspenders and the precast floor slab. When hoisting the precast floor slab, the stability of the precast floor slab can be improved.

[0004] However, in the prior art, although the two suspenders can maintain the same rotation angle, they cannot achieve rotation in the horizontal direction, that is, the distance between the two suspenders cannot be adjusted flexibly, so it is not convenient to adjust the distance between the hooks to adapt to building materials of different widths, resulting in poor overall adaptability and practicability.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention.

[0033] Embodiment 1

[0034] Please refer to Figure 1 As shown, the present invention is a building material hoisting device, including a lifting flat plate 1. Four or more hoisting rings 103 are welded on the upper surface of the lifting flat plate 1. By connecting ropes through the hoisting rings 103, it is convenient to hoist it through a hoisting device, and the hoisting device and the ropes are not shown in the figure.

[0035] As Figure 5 As shown, the lifting flat plate 1 is rotatably connected with four rotating shafts 2 distributed in a rectangle and slidably connected with two sliding plates 3. Among them, the lifting flat plate 1 is provided with four stepped through holes distributed in a rectangle, and the rotating shaft 2 is a stepped shaft structure that cooperates with the stepped through holes one by one. The rotating shaft 2 of the stepped shaft structure is rotationally connected with the stepped hole through a bearing, which is beneficial to providing better axial support for the rotating shaft 2, so as to obtain a larger lifting load and ensure the overall reliability.

[0036] As Figure 2As shown in the figure, a gear 201 is fixedly connected to the upper end of the rotating shaft 2. The lower end of the rotating shaft 2 penetrates through the hoisting flat plate 1 and is hinged to a suspension rod 202, and a hook 203 is connected to the end of the suspension rod 202. Specifically, the hook 203 is hinged to the suspension rod 202, so that the hook 203 can rotate in the vertical plane, and the hook 203 is in a vertical state in the free state. At the same time, the suspension rod 202 is hinged to a connecting seat 205, and the hook 203 is rotatably connected to the connecting seat 205, so that the hook 203 can rotate flexibly, facilitating flexible adaptation to the hoisted building materials.

[0037] Two sliding plates 3 are each fixedly connected with two first gears 301, and the two first gears 301 connected to each sliding plate 3 are respectively meshed with the gears 201 connected to two of the rotating shafts 2, so that the four rotating shafts 2 rotate synchronously in pairs. When adjusting, only need to move the suspension rod 202, and use the transmission between the gear 201 at the upper end of the rotating shaft 2 and the first gear 301 to drive the other rotating shaft 2 to rotate, thereby driving the other one to rotate through the suspension rod 202 to achieve linkage in pairs, that is, only two of the four suspension rods 202 need to be adjusted. When the suspension rod 202 rotates, the distance between the hooks 203 at the ends of the suspension rod 202 is adjusted, facilitating the hoisting of building materials with different widths.

[0038] Preferably, as Figure 3 shown, a transition gear 101 is rotatably connected to the hoisting flat plate 1; second racks 302 meshed with the transition gear 101 are fixedly connected to the opposite ends of the two sliding plates 3, so that the two sliding plates 3 are driven by the transition gear 101 to move synchronously and in opposite directions. Therefore, when any one of the suspension rods 202 is moved, the two sliding plates 3 move synchronously towards or away from each other, so that the other three rotating shafts 2 drive the suspension rods 202 connected thereto to rotate synchronously, so that the four rotating shafts 2 rotate synchronously, that is, by rotating one of the suspension rods 202, the position adjustment of the four suspension rods 202 can be completed, and the two suspension rods 202 are in pairs and the included angle between them is the same, effectively improving the convenience and accuracy of the adjustment.

[0039] Embodiment 2

[0040] As Figure 2 、 5 and 8 shown, on the basis of Embodiment 1, a connecting shaft 204 is fixedly connected to the suspension rod 202 and is rotatably connected to the rotating shaft 2 through the connecting shaft 204. Two transmission shafts 4 are rotatably connected to the lower surface of the hoisting flat plate 1 through bearing brackets, and both ends of the transmission shaft 4 are respectively connected to the connecting shaft 204 connected to the two rotating shafts 2 through telescopic universal shafts 401, so that the four suspension rods 202 rotate synchronously in pairs in the vertical direction.

[0041] That is, when one of the suspension rods 202 is adjusted to rotate in the vertical direction, the suspension rod 202 connected to it through the transmission shaft 4 and the telescopic universal shaft 401 can achieve synchronous rotation, thereby improving the convenience of adjustment. The telescopic universal shaft 401 is used for connection and transmission, which can ensure the rotation of the suspension rod 202 in the vertical direction and the rotation of the suspension rod 202 and the rotating shaft 2 in the horizontal direction.

[0042] As more preferably, Figure 4 , 6 As shown in FIG. 7 , the two transmission shafts 4 are fixedly connected with driving wheels 402 ; the lower surface of the lifting plate 1 is welded or screwed with a mounting plate 102 , and the mounting plate 102 is rotatably connected with two rotating shafts 403 arranged side by side through bearings.

[0043] One end of the two rotating shafts 403 is fixedly connected to a driven wheel 404, and the other end is fixedly connected to a transmission gear 405, and the two driven wheels 404 are respectively connected to the driving wheels 402 connected to the two transmission shafts 4 in a one-to-one transmission connection. The driven wheel 404 and the driving wheel 402 are sprockets or synchronous pulleys, so that the rotation can be guaranteed to be synchronized.

[0044] The two transmission gears 405 mesh with each other so that the two rotating shafts 403 rotate in opposite directions. When one of the booms 202 is adjusted to rotate in the vertical direction, the boom 202 connected to it through the transmission shaft 4 and the telescopic universal shaft 401 can rotate synchronously in the same direction.

[0045] At this time, the transmission shaft 4 drives the driven wheel 404 connected to it to rotate through the driving wheel 402, and the two rotating shafts 403 are transmitted through the mutually meshing transmission gears 405, and the rotation directions of the two rotating shafts 403 are opposite, and the rotating shaft 403 on the other side drives the driving wheel 402 connected to it to rotate through the driven wheel 404 connected to it, that is, by driving the other transmission shaft 4 to rotate, and the rotation directions of the two transmission shafts 4 are opposite, and then the two connected suspension rods 202 are driven to rotate synchronously through this transmission shaft 4, so that the four suspension rods 202 can achieve synchronous rotation, and the rotation angle is consistent, which effectively improves the convenience of adjustment, and ensures that an isosceles triangle is formed between the two adjacent suspension rods 202 and the building materials, thereby ensuring the stability of lifting.

[0046] In addition, a protective cover plate is installed on the lower surface of the lifting plate 1 by screws. The protective cover plate is shown in the figure. The protective cover plate is used to cover and protect the transmission shaft 4, the telescopic universal shaft 401, the driven wheel 404 and the driving wheel 402. During the movement of the lifting plate 1, the transmission shaft 4, the telescopic universal shaft 401, the driven wheel 404 and the driving wheel 402 below are prone to collision, which is beneficial to improve the overall reliability of use and ensure the overall service life.
